The purpose of this paper is to examine how well (or poorly) patients past the age of 60 tolerate intracranial surgery for aneurysms in all locations. The records of 93 consecutive good risk patients (Botterell Grades 1 and 2) have been reviewed. Co-existing chronic medical conditions, e.g., hypertension, were ignored in patient grading. The results indicate that, for treatment of aneurysms on the anterior circulation, older patients tolerate intracranial procedures as well as younger patients. This is not true for operations upon posterior circulation aneurysms. Some possible reasons for this discrepancy are suggested.
本文旨在研究60岁以上患者对颅内各部位动脉瘤手术的耐受情况（无论是良好还是不佳）。回顾了93例连续的低风险患者（Botterell分级为1级和2级）的记录。在患者分级中忽略了并存的慢性疾病，如高血压。结果表明，对于前循环动脉瘤的治疗，老年患者对颅内手术的耐受情况与年轻患者相同。而后循环动脉瘤手术则并非如此。文中提出了造成这种差异的一些可能原因。
